清洁水基压裂液在陕北低渗油田的应用

随着油气资源的开采,地下资源的枯竭,压裂已经成为油气资源进行深层次挖掘的有效手段。但压裂过程中,由于外来压裂液侵入地层,对地层造成污染,严重影响压裂缝面附近基质的渗流能力,降低压裂后油井产能。为了降低压裂液对地层污染,需引进清洁压裂液,降低对地层的伤害。介绍了清洁水基压裂液在陕北低渗油田的应用,重点阐述了清洁水基压裂液性能,并对清洁水基压裂液的现场应用现状进行了简单分析。

The clean water base fracturing fluid used in low permeability reservoir of the north Shannxires of the north Shannxi

With the exploitation of hydrocarbon resources and drying up of hidden resources, fracture has been effective measure in digging hydrocarbon resources.But in the process of fracture,the fracture fluid would intrude into and pollute formation,which seriously affect the filtrate ability of matrix that is in the vicinity of split,decrease deliverability.in order to decrease pollution,we need introduce clean water base fracturing fluid,decrease the harm to formation. this article introduced the clean water base fracturing fluid that used in the north shannxi, elaborated ability of the clean water base fracturing fluid,and analysed apply of present situation.
